A stencil determines a source neighborhood whose points contribute to the position of a refined point. The geometry mask of a stencil specifies the computation on the nodes of the stencil. Sqrt3_mask_3<Polyhedron_3> implements the geometry masks of √3 subdivision on a triangulated Polyhedron_3<Cartesian>.
#include <CGAL/Subdivision_mask_3.h>
The full template declaration of Sqrt3_mask_3<Polyhedron_3> states one template parameter:
| template < | class Polyhedron_3> class Sqrt3_mask_3; |
The only parameter requires a Polyhedron_3 as the argument. The Polyhedron_3 should be specialized with the Cartesian kernel, which defines the Point_3 for the vertices.
| Sqrt3_mask_3<Polyhedron_3> S; | |
|
default constructor.
| |
| void | S.facet_node ( Facet_handle f, Point_3& pt) | |
| computes the √3 facet-point pt of the facet f. | ||
| void | S.vertex_node ( Vertex_handle v, Point& pt) | |
| computes the √3 vertex-point pt of the vertex v. | ||
